Darlot Cone Centralisateur 220mm F4
History: The Cone Centralisateur lens
design (which is a petzval design with a large cone in the rear to avoid reflections), is absolutely famous and sought after in the late 19th
century and even more today. It was the flagship lens for Jamins
and Darlots workshop in the early 1850ies and 1860ies in Paris. It offered better
optical quality then most of his rivals, but also a possibility to it as
a portrait (portrait mode) lens and also as a landscape lens (paysage).
Even though its a petzval design, you will see a slight
difference to other portrait petzvals from that time. The Cone
Centralisateur lenses have this cenrtain 'something' to their image,
which is hard to grasp, but many people are looking for.
The engraving is a bit hard to rear, but one still can see:
'ANCne Mon Jamin - DARLOT St OPTn Bte - 14 r Chapon Paris'
This puts the lens in the small time period right after Darlot took over the workshop from Jamin and engraved his lenses this way from 1862-1863.
Condition: This brass comes in a good condition overall. It shows some wear here and there butalso a warm patina, the rack & pinion mechanism seems complete and moving. The glass is in good condition too, there are some cleaning marks but as always that wont harm the image quality in the slightest. There is no haze, fungus or seperation presendly vissible. The image on the groundglass offers a really sharp center with a nice falloff towards the egdes.
With its fast open aperture of F4 and a focal
lengh of 220mm (or almost 8 1/2"), this lens will work anywhere from 5x7 and fullplate formats.
In landscape mode it will have an estimated focal lenght of 500mm, covering huge ULF formats like 14" x 17" !
It comes with a fitting flange.
